Modules
module	cp_lbfgs_optimizer_gopt
	routines that optimize a functional using the limited memory bfgs quasi-newton method. The process set up so that a master runs the real optimizer and the others help then to calculate the objective function. The arguments for the objective function are physically present in every processor (nedeed in the actual implementation of pao). In the future tha arguments themselves could be distributed.

Functions/Subroutines
subroutine, public	cp_lbfgs_optimizer_gopt::cp_opt_gopt_create (optimizer, para_env, obj_funct, x0, m, print_every, wanted_relative_f_delta, wanted_projected_gradient, lower_bound, upper_bound, kind_of_bound, master, max_f_per_iter, trust_radius)
	initializes the optimizer
subroutine, public	cp_lbfgs_optimizer_gopt::cp_opt_gopt_release (optimizer)
	releases the optimizer (see doc/ReferenceCounting.html)
logical function, public	cp_lbfgs_optimizer_gopt::cp_opt_gopt_next (optimizer, n_iter, f, last_f, projected_gradient, converged, geo_section, force_env, gopt_param, spgr)
	goes to the next optimal point (after an optimizer iteration) returns true if converged
subroutine, public	cp_lbfgs_optimizer_gopt::cp_opt_gopt_stop (optimizer)
	stops the optimization
